SPRINKLER-NOZZLE.

Specification of Letters Patent.

Patented Dec. 21, 1915.

Application filed July 8, 1912. Serial No. 708,193.

To (all whom it In (11/ concern:

lie it known that we, Mxrrnew (iAlfL'l and ALMON L. Fumes, citizens of the United States, residing at \Vorcester, in the county of \Vorcester, State of Massachusetts, have invented a certain new and useful Improvement in Sprinlder-N ozzles of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to sprinklers but more particularly to such as are adapted for use in spreading sewage upon filtration beds.

The object of the same is to provide a simple and inexpensive construction which will more eliiciently perform this work than any of the devices heretofore known.

The many features and advantages of the invention will be fully described hereinafter and included in the claims.

One embodiment of the invention is shown in the drawings in which:

Figure 1 is a side elevation of the invention complete, and Fig. 2, same as Fig. 1,

center section.

Referring to the drawings, the dome or nozzle 10 is provided with a threaded end 11 or other suitable means to permit the same to engage the extremity of a fluid conducting pipe. Within this dome or nozzle 10 is a cross piece 12 centrally mounted in which is the lower extremity of the spreader supporting rod 13. This rod is provided with a locking pin adapted to pass through the slot 15 in the cross piece when the rod is inserted in the nozzle and to lock the rod within this cross piece when this rod is rotated therein. Thisrod passes out through the orifice 16 of the nozzle preferably centrally thereof.

' Upon the rod 13 outside the nozzle is the spreader 17 preferably substantially conical with its apex pointing into the-orifice l6 and its axis coincident with the axis of the nozzle.

Upon the sloping walls of the spreader 17 and preferably at a distance from the apex of the same is a laterally extending projection 18 preferably in the form of a ring or flange either secured thereon or integral therewith. This ring is adapted to receive the impact of the fluid projected upwardly along the surface of the spreader and to cause this fluid to be thrown outwardly practically at right angles to the axis of the nozzle.

\Vhile the present embodiment of the invention comprising a spreader of conical form with a ring flange thereon of the type shown in the drawings is the preferred form thereof, it Wlll readily be seen that a considerable number of different formations having a spreading surface abruptly flaring might be adopted in place thereof, and the applicants do not care to be limited to this particular embodiment.

The particular form of nozzle and method of supporting the spreader opposite to the orifice therein form no part of the present invention and the applicants spreader may be readily used with almost any other type of nozzle.

-\Vhat we claim as our invention and desire to secure by Letters Patent is 1. In a device of the class described, a

substantially dome shaped nozzle, an outlet opening in said nozzle, and a spreader wholly outside said nozzle opposite to said opening having its spreading surface flaring abruptly adjacent to the outer portion thereof, said nozzle having the walls thereof at its mouth at an angle to the axis of the spreader and a recess surrounding the mouth.

2. In a device of the class described, a substantially dome shaped nozzle, an outlet opening in said nozzle, and a conical spreader wholly outside said nozzle opposite said opening having its conical wall abruptly flaring adjacent to the base of the cone, said nozzle having the walls thereof at its'mouth inclined inwardly toward the axis of the spreader and a recess surrounding the mouth.

3. In a device of the class described, a

-. substantially dome shaped nozzle, an outlet opening in. said nozzle, and a spreader wholly outside said nozzle opposite to said opening substantially conical in form and having about its conical surface adjacent to the base of the cone a laterally extending projection, said nozzle having the walls thereof at its mouth at an angle to the axis of the spreader and a recess surrounding the mouth.

4. In a device of the class described, a substantially dome shaped nozzle, an outlet opening in said nozzle, and a spreader wholly outside said nozzle opposite to said opening substantially conical in form, and

substantially dome shaped nozzle, a body wholly outside said nozzle and oppositely disposed to said nozzle adapted to turn the.

fluid issuing from said nozzle at an acute angle to the axis of said nozzle, and means for abruptly turning said fluid away from said body at substantially a right angle to 15 said axis, said nozzle having the walls thereof at its mouth at an angleto the axis of the spreader and a. recess surrounding the mouth.

In testimony whereof we afiix our signa- 2 0 tures in the presence of two witnesses.
